I can't find it there (glibc 2.2.5 Debian GNU/Linux). What's the
version of your C library that you're using?
Usually, in order to get unbuffered line input you need to switch the
terminal to unbufferd input mode (and properly restore it when done -
I guess this wouldn't work with a simple macro; I'd really like to see
the macro if it really is there).
Here's some code I used for this purpose:
,----
| struct termios tio_orig;
| struct termios tio_new;
|
| tcgetattr(0, &tio_orig);
|
| tio_new = tio_orig;
| tio_new.c_lflag &= ~(ICANON|ECHO); /* Clear ICANON and ECHO. */
| tcsetattr(0,TCSANOW,&tio_new);
|
| /* ... */
|
| tcsetattr(0,TCSANOW,&tio_orig);
`----
Cheers.
